[Bug]: Invalid transaction params Error after switching account and network (EIP-1559 mismatch)

**Describe the bug**

After switching from a non-EIP-1559 network to an EIP-1559 network inside a connected Dapp, MetaMask continues to use outdated transaction parameters and throws an error:
`Invalid transaction params: params specify an EIP-1559 transaction but the current network does not support EIP-1559`

**The issue persists until the MetaMask extension icon is clicked (which seems to refresh the internal state).**

**Expected behavior**

MetaMask should automatically update its internal transaction type and network context when switching between networks with/without EIP-1559 support, without requiring a manual refresh

**Steps to reproduce**

1. Connect wallet A to a network B that **does not** support EIP-1559
2. Perform an approve transaction, then revoke (cancel) it
3. In **MetaMask extension**, switch account (select another account)
4. Connect the new account to the Dapp
5. **In the Dapp**, switch network to one that supports EIP-1559 (e.g. Gnosis or any other)
6. Try to perform a new transaction (approve, send, etc.) **The gasPrice / estimateFees value is passed into the transaction.**

**Detection stage**

In production (default)

**Version**

13.7.0

**Build type**

None

**Browser**

Chrome

**Operating system**

MacOS

**Additional context**

**DEMO REPO**
https://github.com/Pasha8914/metamask-switch-account-issue

**The error remains until you click on the MetaMask extension icon (which forces an internal refresh).
After that, transactions work as expected.**

Start with the reproduction steps and DEMO REPO, then inspect the App.tsx:97:20 transaction path alongside the account and network switching behavior. Compare transaction parameters before and after switching, and consider the issue done when transactions succeed without clicking the MetaMask extension icon.
